Condensing boiler

Uses the latent heat of exhaust gas vapors. The efficiency of such boilers reaches 107-109% compared to the average efficiency of traditional non-condensing gas boilers. Condensing gas boilers allow you to save up to 20-25% of fuel during the heating season, which means saving you and your customers money

Turbocharged boiler

Depending on the design solution of the boiler room, it allows organizing an air supply and smoke exhaust system through the wall.
Heating and hot water (in combination with a DHW cylinder)

Can be used in low temperature radiant and panel radiant heating systems

Suitable for reconstructed and under construction houses and apartmentsIdeal for building compact rooftop boilers

Possibility of using combustion air both from inside and outside

Work with own certified chimney/air duct systems
Gas wall-mounted heater using the latent heat of condensation

Burner modulation range from 10 to 100%

Advanced DIA-system (digital information and analytical system) for simplified diagnostics

NOx class - 6

Standard efficiency - 98% (Hs) / 109% (Hi)

Prepared for connecting a DHW cylinder (selected separately)

Equipment

High efficiency pump

Water pressure sensor, volumetric flow sensor, pressure gauge, 10-litre expansion tank, safety relief valve

Stainless steel condensing heat exchanger
